Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Bcl2-A1 interacts with pro-caspase-3: Implications for amyotrophic lateral sclerosis
Neurobiology of Disease, 2011 Expression of mutant SOD1 typical of familial amyotrophic lateral sclerosis (ALS) induces the expression of Bcl2-A1, a member of the Bcl2 family of proteins, specifically in motor neurons of transgenic mice.In this work, we have used immortalized motor ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Structural biology of bacterial response regulator proteins and their complexes with cognate ligands [PDF]
, 2009 Two bacterial response regulator systems were studied in this thesis. NMR spectroscopy and X-ray crystallography were used to determine the structures of both domains of the antibiotic sensor TipAL, as well as of the c-di-GMP receptor PA4608, in ...

Hsp70 at the membrane: driving protein translocation
BMC Biology, 2018 Efficient movement of proteins across membranes is required for cell health. The translocation process is particularly challenging when the channel in the membrane through which proteins must pass is narrow—such as those in the membranes of the ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

An archaellum filament composed of two alternating subunits
Nature Communications, 2022 The archaellum is a molecular machine used by archaea to swim, consisting of an intracellular motor that drives the rotation of an extracellular filament composed of multiple copies of proteins named archaellins.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

cDNA that encodes active agrin [PDF]
, 1992 Agrin is thought to mediate the motor neuron-induced aggregation of AChRs and AChE on the surface of muscle fibers at neuromuscular junctions. We have isolated a cDNA from a chick brain library that, based on sequence homology and expression experiments,

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
